This study examined the effects of support systems and traditional value beliefs about the role of women on the parenting stress of dual-career mothers. The subjects were 203 employed mothers with one child 4- to 36-months of age. The influential independent variables affecting parenting stress listed in order of significance were satisfaction with child care, value placed on traditional maternal roles, sex of child, and cost of child care. Contrary to the researchers assumptions, social support systems had no effect on parenting stress. The results of this study have implications for formal and informal support systems for employed mothers with young children.

This study attemps to identify the factors related to dealing withy work-family conflict of employed women, and to investigate the needs and the methods of support for household labor. Especially, the results of this study aims to be reflected in women's policy from a political point of view. For these purposes, 477 married women those being employed (more than 30 hours per week) and having nuclear family were selected. Statistics were frequencies, means, percentile, and two-way ANOVA. The results were as follows. First, employed mother's housework time is 5 hours 16 minutes on a weekday and 9 hours 32 minutes on Sunday with the exception of market work time. And 84.5% of total housework was performed by housewife. Thus they take chage of work burden(market work and housework), and make a difficulties of cooking and family care. Seconds, the highest needs of support was the change of thought on division of labor, responsibility on housework, and status of women. The next were the needs of the social organization(flex-time, a special holiday for woman workers, home-based work) and the public institution(day-care center, school feeding). Thirds, contributing factors to the needs of support were housewife's age and occupation. So, this two factors were crossed in order to analyze family type by factors.

The purpose of the current study is to examine the role of mothers' personality traits in predicting their parenting stress. The study subjects were married working woman who live at Gyeonggi-do and has their first child studying in elementary, middle, or high school. Collected data were analyzed with SPSS WIN 18.0 program. The results were as follows.: First, it has been shown through examination of the general tendency of observation subjects' relative factor, that many have above average parenting stress. The compositing factor for parenting stress were mainly the burden and distress of the parent role. Second, the differences in parenting stress were affected by relative variables in accordance with the general features of the study object. If the younger the parent, the higher the education, the lower the age of the first child, and if there were a child assistant after school, the parenting stress became larger. Third, after controlling for demographic characteristics, employed mothers' neuroticism significantly predicted greater parenting stress. When mothers had more conscientiousness and openness, they reported less parenting stress which implied that interpretation and perception of child rearing experiences can vary depending on personality and predict parenting stress of working mothers.

Objectives: The purpose of the this study is to investigate parenting stress of married dental hygienists having preschool and school aged children. Methods: A self-reported questionnaire was completed by 242 married dental hygienists from September to December, 2015 via e-mail and ordinary mail. The questionnaire consisted of demographics, job-related characteristics, family life satisfaction, and parenting stress. The data were analyzed using Stata 13.0 program. Results: As for job-related characteristics, 36.6% of the subjects answered 'not possible' in work hour flexibility. The reasons why family-work balance is difficult were 'parenting and education(58.7%)' and 'burden of family-work balance(32.4%)'. Family life satisfaction was 3.03, and parenting stress was 2.41. Parenting stress gets higher if their children are younger, monthly income is lower, and mother/father's age are lower. And parenting stress becomes higher if their career as dental hygienists is less, they are contract worker, and frequency to change jobs is higher. Concerning the reason why work-family balance is difficult, parenting stress is found to be high when they choose 'parenting and education', 'burdens of work-family balance', and 'relationship in workplace'. Family life satisfaction reduced parenting stress. According to the results of multiple linear regression analysis, frequency to change job influences parenting stress. Conclusions: Parenting stress increases turnover and career interruption of married dental hygienists. It is hard to improve work environment without policy support. It will be necessary to establish policy for employed mothers and create a work atmosphere where the policy can be utilized without difficulty.

This paper proposes a feature extraction method using wavelet transform for speech recognition. Speech recognition system generally carries out the recognition task based on speech features which are usually obtained via time-frequency representations such as Short-Time Fourier Transform (STFT) and Linear Predictive Coding(LPC). In some respects these methods may not be suitable for representing highly complex speech characteristics. They map the speech features with same may not frequency resolutions at all frequencies. Wavelet transform overcomes some of these limitations. Wavelet transform captures signal with fine time resolutions at high frequencies and fine frequency resolutions at low frequencies, which may present a significant advantage when analyzing highly localized speech events. Based on this motivation, this paper investigates the effectiveness of wavelet transform for feature extraction of wavelet transform for feature extraction focused on enhancing speech recognition. The proposed method is implemented using Sampled Continuous Wavelet Transform (SCWT) and its performance is tested on a speaker-independent isolated word recognizer that discerns 50 Korean words. In particular, the effect of mother wavelet employed and number of voices per octave on the performance of proposed method is investigated. Also the influence on the size of mother wavelet on the performance of proposed method is discussed. Throughout the experiments, the performance of proposed method is discussed. Throughout the experiments, the performance of proposed method is compared with the most prevalent conventional method, MFCC (Mel0frequency Cepstral Coefficient). The experiments show that the recognition performance of the proposed method is better than that of MFCC. But the improvement is marginal while, due to the dimensionality increase, the computational loads of proposed method is substantially greater than that of MFCC.

This study analyzed the effect of parent-child communication and peer relationship on children's internet addiction. The subjects were 642 elementary school students living in Daejeon city. Cronbach's $\alpha$, t-test, ANOVA, and Duncan's test were employed in analyzing the data by using SPSS 10.0. The findings of this study were as follows First, the boys were more addicted to internet use than the girls, as were the children of less educated parents. The children of parents with professional careers were less addicted to the internet. The children who perceived their school achievements as low were more addicted to the internet. Second, the children who spent more time daily, longer time at once and more frequently per weekly internet use were more addicted. Third, internet addiction was influenced tv parent-child communication and peer relationship. Boys who had more problem communications with their parents less open communication with their mother and a lower level of peer support were more addicted to the internet. The problem of communication with their mother and conflict in their peer relationship had more influence on the internet addiction of girls.

The purpose of this study was to compare the dietary behavior of middle school and high school students who had working mothers with students whose mothers were not employed. Self-reports on their dietary behavior and one-day dietary records were obtained from 396 middle school students and 364 high school students using anonymous questionnaires. The results were summarized as follows; the students with working mothers were more likely to not to eat properly and their dietary behavior was generally inadequate, showing a greater irregularity for meals, more of a tendency to skip breakfast, less diversity of food intake, and a higher incidence of drinking and smoking. One-day dietary records obtained by 24k recall methods showed less diverse food intake and a higher rate of skipped meals in students with working mothers. Drinking and smoking were more prevalent among middle school students whose mothers were working than among those students with unemployed mothers, but in the case of high school student the difference was not significant. With more and more housewives seeking jobs, more attention needs to be given to the dietary and nutritional intake of their children, especially among middle school students. High school students seem to be less affected than middle school students by their mother's employment.

As the Korean school entry date changed in 2010, from March 1 to January 1, January-born children are older than their peers at school, and December-born children are the youngest. This implies that parents may have incentives to avoid giving birth in December, and a mother who gives birth in this month is likely to be a mother who is not very concerned with her child's education. This study finds that the mothers of December-born children are younger, have lower education level, and have a lower probability of being employed than other mothers. This means that December-born children are more disadvantaged because they are the youngest among their peers and are from families of low socioeconomic backgrounds.

This research was based on achievement goal theory which categorizes young children's motivation into three types: mastery, the performance-approach, and performance-avoidance motivation. The participants consisted of forty-eight pairs of children aged 3-4 and their mothers. The participants completed two tasks in order to indentify their motivational types. The short form of the Child Behaviour Questionnaire(CBQ-SF), modified scales from Kim and Kim(2001), and the GIPEPS were also employed. The major findings of the research are as follows: First, in terms of the motivational types of the given sample, performance-approach motivation was ranked first followed by mastery motivation. Second, it was found that the temperament of young children was not related with their motivational types. Third, there were some differences in mother-child interaction between groups based on the frequency of feedback, questions, and the percentage of commands. Fourth, the mood of the relationship appeared to be the only factor of maternal interaction quality which related to children's mastery motivation.

Congenital heart disease is now estimated to be the most prevalent chronic illness in children. The overall purpose of study is to enhance our understanding of mother's perception of family stress, perceived social support, and coping who has a child newly diagnosed with congenital heart disease. In this investigation, the relationship between family stress, perceived social support, and coping within the context of a acute, non life- threatening chronic illness in the situation of newly diagnosed as Rolland's typology of chronic illness. The study employed data from a subset of a large longitudinal study, children's chronic illness: parents and family adaptation conducted by M. McCubbin (5 R29 NR02563) which was funded by the NIH. The subject for this study were 92 mothers who have a child under age 12 who was newly diagnosed with congenital heart disease within the last 3-4 months. Results form correlational and regression analysis revealed that perceived social support operated as a resiliency factor between family stress and coping of mothers. Child and family characteristics appeared to be important predictors of perceived social support and mother's coping. Therefore, the findings provide an incremental contribution to the explanation of effects for perceived social support and may challenge resiliency model in previous literature. Further, these findings suggest that perceived social support and coping are both influencing in the resiliency of relatively high risk groups of families who has a child with congenital heart disease.
